Project Description:
The east and west campus areas of the University of Nebraska at Kearney were served by a central heating system originating from two plants, one constructed in the 1930s. Both plants housed boilers and one contained a chiller. The majority of the steam piping was routed through walk-through tunnels. Chilled water piping was routed through walk-through tunnels and was also direct buried. The new central plant houses 4-boilers and 2-chillers. The purpose of the project was to expand and enhance the central system to provide additional capacity and reliability. Some existing tunnels were replaced and more tunnels were added to distribute the Hydronic Piping throughout the campus. The new campus distribution piping was either routed through the existing / new tunnels or was direct buried. The new distribution system was installed alongside the old system in these tunnels as to facilitate little downtime or disruption to the campus. Some mentionable system components are:
-(2) 900 hp Superior Super Seminole 3-pass wetback boilers
-(1) 600 hp Superior Super Seminole 3-pass wetback boiler
-(1) Precision HVJ electrode boiler 9,900 Pounds Per Hour
-(1) BFS Tray Deaerator and Surge Tank
-(2) 1332 ton York centrifugal liquid chillers
-(4 ) Tower Tech Modular Fiberglass Cooling Towers
-(1) Puroflux Sand Filter, 475 gpm, 1425 gal capacity
-5,000 Lin. Ft of Campus distribution Piping
